I apologize, I misunderstood your post. Usually when people link to other threads they say "use the search function we already have this" instead of helping. Just getting fed up with people being jerks in the forum.

What do you mean by temporary? Is it just for you and some friends? If it is you can really just lay some fold out tables on there side. My backyard is the same size as your and it gives basically no room to play though.
